Technical Field
[0001] This application relates to the field of assembly and fitting, and in particular to bending test fixtures and workbenches. Background Technology
[0002] An optical filter is an optical element that selectively transmits or reflects light within a specific wavelength range to adjust optical signals. During filter production, to ensure filter performance and quality, each filter typically undergoes a filter strength test. However, existing filter models use different sizes, requiring varying testing spans and support positions. When multiple models need to be produced, current equipment cannot meet the testing requirements for all models.
[0003] Therefore, there is a need for an intensity testing device that can be adapted to filters of multiple sizes. Utility Model Content

The fourth mounting position is located in front of the third mounting position and is higher than the third mounting position. The fourth mounting position has a second support line, which provides a second support position for the product under test.

At least a portion of the second limiting block overlaps with the fourth mounting position. At the third mounting position, the second limiting block slides with the second support member. By adjusting the distance between the first limiting block and the second limiting block, the fixture can accommodate different specifications and dimensions of the products under test.

A first support member is mounted on the first support plate and located at one end of the first guide rail. A second support member is mounted on the first slider. By moving the first slider, a preset distance is left between the first support member and the second support member, thereby adjusting the position of the first support position and the second support position acting on different products under test.
[0009] The bending test fixture includes a second support plate and a second linear slide rail slider assembly. The second linear slide rail slider assembly includes a second guide rail and a second slider that slides with the second guide rail. The second guide rail is mounted on the second support plate, and the first support plate is mounted on the second slider.
[0010] The bending test fixture includes a first micrometer, which passes through a first connecting plate and connects to a second connecting plate. The first connecting plate and the second connecting plate are spaced apart, and the first connecting plate and the first micrometer are locked together. The first connecting plate abuts against one side of a second support plate to limit the movement of the first micrometer relative to the second support plate. The second connecting plate connects to one side of the first support plate, and the second connecting plate and the second support member together limit the extreme position of the first slider relative to the first guide rail. By screwing the first micrometer, the second connecting plate pushes the first support plate to move.
[0011] The bending test fixture includes a second micrometer, which is used to connect to the second connecting plate.

Furthermore, it can avoid interference problems between filters of different sizes and the first limiting block or the second limiting block, so as to facilitate the bending test fixture to be adapted to the application of filters of different sizes.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0029] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptions used in this text have been explained accordingly.
[0030] As an optical element, a filter selectively transmits or reflects light within a specific wavelength range to adjust optical signals. During filter production, to ensure performance and quality, each filter typically undergoes a strength test. However, existing filter models use different sizes, requiring varying testing spans and support positions. When multiple models need to be produced, current equipment cannot meet the testing requirements for all models.
[0031] In other words, existing simple filter strength testing equipment can only be used with filters of a single size. In actual production, filter sizes vary widely, with one testing machine corresponding to one filter size. This means that multiple types of filters require multiple models and sizes of existing testing equipment, resulting in extremely cumbersome testing procedures and very low testing efficiency. Therefore, a strength testing device that can adapt to multiple filter sizes is needed.
[0032] To alleviate the above problems, refer to Figures 1-5 This application provides a bending test fixture and workbench, which can perform bending tests on filters of different sizes on the same machine. Furthermore, the width of the test position can be adjusted at any time according to the different sizes of the filters to further adapt to the bending test applications of filters of different sizes.
[0033] Specifically, the bending test fixture provided in this application includes: a first support member 1, a second support member 2, a first limiting block 3, and a second limiting block 4. The first support member 1 includes a first mounting position 11 and a second mounting position 12. The second mounting position 12 is located in front of the first mounting position 11 and is positioned higher than the first mounting position 11. The second mounting position 12 has a first support line 12111, which provides a first support position for the product under test. The second support member 2 includes a third mounting position 21 and a fourth mounting position 22, with the fourth mounting position 22 located in front of the third mounting position 21. The fourth mounting position 22 is set higher than the third mounting position 21. The fourth mounting position 22 has a second support line 22111, which is used to provide a second support position for the product under test. The first limiting block 3 is at least partially connected to the second mounting position 12. At the first mounting position 11, the first limiting block 3 and the first support member 1 are slidably engaged. The second limiting block 4 is at least partially connected to the fourth mounting position 22. At the third mounting position 21, the second limiting block 4 and the second support member 2 are slidably engaged. By adjusting the distance between the first limiting block 3 and the second limiting block 4, the specifications and dimensions of different products under test can be adapted.
[0034] In this way, the first limiting block 3 can slide relative to the first support 1, and the second limiting block 4 can slide relative to the second support 2. That is, by adjusting the positions of the first limiting block 3 and the second limiting block 4, the contact position between the edge of the product to be tested and the first limiting block 3 or the second limiting block 4 can be directly adjusted. In other words, the space between the first limiting block 3 and the first support line 12111 of the first support 1 is adjusted, and the space between the second limiting block 4 and the second support line 22111 of the second support 2 is adjusted. Furthermore, interference problems between filters of different sizes and the first limiting block 3 or the second limiting block 4 can be avoided.
[0035] For example, during the bending test, the first support line 12111 is one of the positions on the second mounting position 12 used to provide bottom-up support force to the product under test.
[0036] For example, during the bending test, the second support line 22111 is another location on the fourth mounting position 22 for providing bottom-up support to the product under test.
[0037] Correspondingly, in order to meet the requirements of the three-point bending test, the central area of the filter also bears the pressing or punching force from top to bottom, so that the three-point bending test can be carried out normally.
[0038] Considering the driving scheme for the sliding movement of the first limiting block 3 relative to the first support member 1, the bending test fixture provided in this application embodiment includes: a first connecting piece 5 and a first differential head 7. The first connecting piece 5 is installed on the side of the first support member 1 near the first mounting position 11. The first differential head 7 passes through the first connecting piece 5 and connects to the first limiting block 3. The first differential head 7 and the first connecting piece 5 are locked together. That is, the first connecting piece 5 is used to support the first differential head 7, and the first differential head 7 passes through the first connecting piece 5 and is locked together with the first limiting block 3.
[0039] By turning the first micrometer head 7, the reciprocating sliding of the first limiting block 3 relative to the first support member 1 can be adjusted, thereby adjusting the distance between the first limiting block 3 and the first support line 12111.
[0040] Considering the driving scheme for the sliding movement of the second limiting block 4 relative to the second support member 2, the bending test fixture provided in this application embodiment further includes: a second connecting piece 6 and a second differential head 8, wherein the second connecting piece 6 is installed on the side of the second support member 2 near the third mounting position 21, and the second differential head 8 passes through the second connecting piece 6 and connects to the second limiting block 4, and the second differential head 8 is locked and assembled with the second connecting piece 6. That is, the second connecting piece 6 is used to support the second differential head 8, and the second differential head 8 passes through the second connecting piece 6 and is locked and assembled with the second limiting block 4.
[0041] By turning the second micrometer head 8, the reciprocating sliding of the second limit block 4 relative to the second support member 2 can be adjusted, thereby adjusting the distance between the second limit block 4 and the second support line 22111.
[0042] Considering the specific design of the second mounting position 12 on the first support member 1 for sliding assembly with the first limiting block 3, in the bending test fixture provided in this application embodiment, the second mounting position 12 is constructed as a first stepped groove 121, wherein the first stepped groove 121 includes a first support side 1211, the top surface of the first support side 1211 is constructed as the aforementioned first support line 12111, the first support line 12111 is used to provide a first support position; similarly, the fourth mounting position 22 is constructed as a second stepped groove 221, the second stepped groove 221 includes a second support side 2211, the top surface of the second support side 2211 is constructed as the aforementioned second support line 22111, the second support line 22111 is used to provide a second support position.
[0043] This application does not limit the specific shape and size of the first stepped groove 121 and the second stepped groove 221, as long as the sliding assembly application of the first limiting block 3 and the second limiting block 4 can be realized.
[0044] For example, the first support side 1211 and the second support side 2211 are protruding structures on the first stepped groove 121 and the second stepped groove 221, respectively, for providing the first support line 12111 and the second support line 22111.
[0045] Considering the specific sliding scheme between the first support member 1 and the second support member 2, the bending test fixture provided in this application embodiment also includes a first support plate 9 and a first linear slide rail slider assembly 10. The first linear slide rail slider assembly 10 includes a first guide rail 101 and a first slider 102 that slides with the first guide rail 101. The first guide rail 101 is installed on the first support plate 9, the first support member 1 is installed on the first support plate 9 and is located at one end of the first guide rail 101, and the second support member 2 is installed on the first slider 102. By moving the first slider 102, a preset distance is left between the first support member 1 and the second support member 2, thereby adjusting the position of the first support position and the second support position acting on different products to be tested.
[0046] By introducing the first linear slide rail slider assembly 10, the reciprocating sliding direction of the second support member 2 can be defined along the direction of the first guide rail 101. That is, the first guide rail 101 can provide a guiding function for the second support member 2, thereby ensuring that the second support member 2 can also ensure the parallelism of its edge relative to the first support member 1 during the sliding process. This further avoids the situation where the distance between the two is too large to place the product under test, or the situation where the distance between the two is too small to cause squeezing damage to the product under test.
[0047] Considering the specific sliding scheme of the first support plate 9, the bending test fixture provided in this application embodiment also includes a second support plate 11A and a second linear slide rail slider assembly 12A. The second linear slide rail slider assembly 12A includes a second guide rail 12A1 and a second slider 12A2 that slides with the second guide rail 12A1. The second guide rail 12A1 is mounted on the second support plate 11A, and the first support plate 9 is mounted on the second slider 12A2.
[0048] By introducing the second linear slide rail slider assembly 12A, the reciprocating sliding direction of the first support plate 9 can be defined along the direction of the second guide rail 12A1. That is, the second guide rail 12A1 can provide a guiding function for the first support plate 9, thereby ensuring that the first support plate 9 will not deviate during the sliding process.
[0049] To ensure that the pressure point in the filter bending test application of the bending test fixture does not shift on the filter, the bending test fixture provided in this application embodiment further includes a first micrometer 13. The first micrometer 13 passes through the first connecting plate 14 and connects to the second connecting plate 15. It should be noted that the first connecting plate 14 is located on the side closer to the first micrometer 13, and the second connecting plate 15 is located on the side of the first connecting plate 14 away from the first micrometer 13. In addition, the first connecting plate 14 and the second connecting plate 15 are spaced apart. The first connecting plate 14 is locked and assembled with the first micrometer 13; the first connecting plate 14 is used to abut against one side of the second support plate 11A to limit the movement of the first micrometer 13 relative to the second support plate 11A; the second connecting plate 15 is used to connect to one side of the first support plate 9, and the second connecting plate 15 and the second support member 2 are used together to limit the extreme position of the movement of the first slider 102 relative to the first guide rail 101; by screwing the first micrometer 13, the second connecting plate 15 pushes the first support plate 9 to move.
[0050] In this way, within the same test fixture, after adjusting the distance between the first limiting block 3 and the second limiting block 4, the relative positions of the first limiting block 3 and the second limiting block 4 can be fixed, and then the position of the filter relative to the pressure point between the first limiting block 3 and the second limiting block 4 can be adjusted as a whole. The adjustment of the pressure point position can be achieved by turning the first micrometer 13.
[0051] Considering the adjustment process of bending test dimensions, the specific adjustable scheme between the first support member 1 and the second support member 2 can be prioritized. In the bending test fixture provided in this application embodiment, the bending test fixture includes a second micrometer 16, which is used to connect with the second connecting plate 15. The second micrometer 16 and the first micrometer 13 are located on the same side of the second connecting plate 15. The second connecting plate 15 is connected to the second support member 2 through the first elastic member 17. The second micrometer 16 is used to adjust the interval position of the second support member 2 relative to the first support member 1.
[0052] In this way, by turning the second micrometer 16, the relative distance between the first support member 1 and the second support member 2 can be adjusted first, making it easier to place the product to be tested on the plane where the first support line 12111 and the second support line 22111 are located. Then, by turning the first micrometer head 7 and the second micrometer head 8, the positions of the first limit block 3 and the second limit block 4 can be adjusted. At this time, the product to be tested can be properly clamped between the first limit block 3 and the second limit block 4, and the product to be tested can be in contact with the first support line 12111 and the second support line 22111 respectively. Furthermore, by turning the first micrometer 13, the first support member 1, the second support member 2, the first limit block 3 and the second limit block 4 can be moved as a whole to adjust the pressure point to fall on the middle area of the product to be tested.
[0053] Considering the specific sliding schemes of the first limiting block 3 and the second limiting block 4, the bending test fixture provided in this application embodiment further includes: a third linear slide rail slider assembly 18 and a fourth linear slide rail slider assembly 19. The third linear slide rail slider assembly 18 includes a third guide rail 181 and a third slider 182 that slides with the third guide rail 181. The third guide rail 181 is installed at the first mounting position 11, and the first limiting block 3 is installed on the third slider 182. The fourth linear slide rail slider assembly 19 includes a fourth guide rail 191 and a fourth slider 192 that slides with the fourth guide rail 191. The fourth guide rail 191 is installed at the third mounting position 21, and the second limiting block 4 is installed on the fourth slider 192.
[0054] By introducing the third linear slide rail slider assembly 18, the reciprocating sliding direction of the first limiting block 3 can be limited along the direction of the third guide rail 181. That is, the third guide rail 181 can provide a guiding function for the first limiting block 3, thereby ensuring that the first limiting block 3 can also ensure the parallelism of the edge of the first limiting block 3 relative to the first support line 12111 during the sliding process, and further avoid damage to the product under test.
[0055] By introducing the fourth linear slide rail slider assembly 19, the reciprocating sliding direction of the second limiting block 4 can be defined along the direction of the fourth guide rail 191. That is, the fourth guide rail 191 can provide a guiding function for the second limiting block 4, thereby ensuring that the second limiting block 4 can also ensure the parallelism of the edge of the second limiting block 4 relative to the second support line 22111 during the sliding process, and further avoid damage to the product under test.
[0056] Considering the source of force at the pressure point above the filter, the bending test fixture provided in this application embodiment further includes: a pressure head 20, which is located above the spaced position between the first support member 1 and the second support member 2, and is used to press down on the product to be tested from top to bottom.
[0057] For example, the pressure head 20 can be an adjustable pressure head 20 that adjusts the applied pressure, or it can be a fixed pressure head 20 that has a preset pressure according to preset requirements.
[0058] In this solution, the pressure head 20 can have an adjustable direction function, or it can be fixed in one position as needed. Combined with other structures in the embodiments of this application, the pressure head 20 can be used to apply pressure from top to bottom to the central area of the filter.
[0059] This application also provides a workbench, including the bending test fixture described above, which can achieve all the effects of the bending test fixture, and will not be described in detail here.
